Light environment is one of the important physical environmental factors indispensable to plant growth and development. Controlling plant morphogenesis through light quality regulation is an important technology in the field of protected culture.
As the fourth generation of new lighting source, led grow lights have many characteristics different from other electric light sources, which also makes it the first choice of energy saving and environmental protection light sources. led grow lights used in the field of plant culture also show the following characteristics: a variety of wavelength types, just in line with the spectral range of plant light synthesis and photomorphogenesis; Spectrum width of half width, can be combined according to the need to obtain pure monochromatic light and composite spectrum; It can focus the light of specific wavelength to illuminate crops evenly. It can not only regulate the flowering and setting of crops, but also control the plant height and plant nutrients. The system produces less heat and takes up less space, which can be used in multi-layer cultivation stereo combination system to achieve low heat load and miniaturization of production space. In addition, its strong durability also reduces operating costs. Because of these remarkable characteristics, led grow light is very suitable for plant cultivation in controlled facility environment, such as plant tissue culture, facility horticulture and factory seedling breeding, and aerospace ecological life protection system.
led grow light is attracting the attention of the world for its inherent advantages. Especially in the context of the global energy shortage worries rising again, due to the LED plant light source has high luminous efficiency, long service life, safety and reliability, environmental protection and energy saving characteristics, so that the prospect of LED plant light in the lighting market has attracted more global attention.
Plants depend on light energy for photosynthesis to grow, blossom and bear fruit. However, due to the ever-changing climate changes and light changes in nature, plants in different growth periods can not fully absorb the photosynthetic nutrients needed during their different growth periods, which brings disadvantageous growth, especially in the seedling stage. In this regard, scientific and reasonable artificial spectrum for the growth of plants to create a good absorption and reflection conditions. The energy values of the blue and red regions, which are very close to the efficiency curve of plant photosynthesis (especially significant for green plants), are the best light source for plant growth.
